ORE-CAR.

Application filed Ju1y25,

To all whom 'it may concern:

Be it-known that I, ARGYLE CAMPBELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new` and useful Improvement in Ore-Cars, of which the following is a full, clear, concise, and eXact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in ore cars.

One object of the invention is to provide an ore car which is adapted to be used with a num'ber of similar'ore cars in a train to dump the ore into the pockets of the ore docks, each car being so designed that it is adapted to dump the ore into two adjacent ore dump pockets and in a train of cars on the dock, two pockets out of every three will be dumped into.

Another object of the invention is to providea car of the above indicated type having a larger capacity than those heretofore generally used in such service,'the increased capacity-being obtained by mounting the doors in a manner hereinafter specified.

A further object of the invention is `to provide operating mechanism for the doors so arranged that it can be operated with equal facility from either side of the car.

The invention furthermore consists in the improvements in the paits and devices and in the novel combination of the parts and devices herein shown, described or claimed.

In the drawing forming a part of this specification, Figure 1 isa part central vertical section and part side elevation of a car embodying my improvements, the left hand end of the car as viewed in Fig. l being in section and the right hand end in elevation. This figure also illustrates the relation of the car length to the spacing between the ore dock pockets and the relative location of the hoppers in the car. Fig. 2 is a top plain view of one-half of the car, parts being broken away to more clearly illustrate the construction. Fig. 3 is a vertical sectional view of the car, the left han'd half of the figure being a section at the center of the car on line AA of Fig. 1 and the right Specification of Letters Patent.

Patented Mair. ae, rara.. 1914. seriaiimssasea hand half being a'section on the line B B of Fig. l. Fig. 4 is a vertical transverse sectional view taken substantially on the line l C of Fig. l, one of the hopper doors being shown in closed position and the other 1n open position. Fig. 5 is a detail view showing the arrangement of one of the latch and ratchet devices employed in the door operating mechanism and Fig. 6 is a similar view illustrating part of the door operating mechanism, particularly the winding drum and links connected to the door.

In the ore carrying service, it is a common practice to ship the ore in cars and to run the train of cars on to an ore dock which is provided with a plurality `of pockets which are l2 ft. from center to center. Hitherto, 24 ft. cars have been generally used in this service with the result that the ore could only be dumped into alternate pockets of the dock, it being understood that the ends of the car and the couplers and draft gear require an amount of space which corresponds to approximately half the length of a pocket. These portions of the cars may be termed non-productive inasmuch as they cannot be utilized for the carrying of the ore. lVith my invention, I provide a car which is approximately 36 ft. long from `center to center of the couplers and the same is arranged with two hoppers equally spaced from the longitudinal center of the car so that each hopper is adapted to dump into a pocket. Vith a cai' of this construction, the operating company derives a bigger advantage due to the fact that a decreased num-V ber of cars have to be operated; an lincreased percentage of the lore or other material is hauled relative to the non-productive load of the car body; and the spacing ofthe two hoppers of my improved car is such that when it is employed in a train having cars of length of a'lesser multiple of the distance from center to center of the receptacles or pockets into which the load is to be dumped and which are capable of dumping into alternate receptacles only, the loadmay be dumped from the two hoppers of my improved car into two adjacent receptacles without interference.

In the drawing, the car body designated fil generally by the reference D and, as shown in Fig. l, its length from center to center of the' couplers is approximately 36 ft. The sleepers of the ore dock are designated by the reference l0, and as shown, the same are substantially 2 ft. square and are spaced apart, l:enter to center, approximately 12 ft. which is the standard practice. The car D, as shown, is provided with side sills 11-11 which are in the form of channels, there being two channels on each side of the c'ar oppositely faced and united by a top plate 12. Vertical end sheets 13 are provided at each endof the car. As clearly shown in Fig; l, the car maybe considered as constituted of two like halves one on each side of the longitudinal center, and inasmuch as each part or half is the same, I shall only describe one'of thema Each halfl of the car is provided with a hopper or pocket E which is formed by side walls 14-l4 inclined at their lower end as indicated; at 15; an inclined inner end wall 16 and an inclined outer end wall 17, the end walls 1G and 17 being extended to a point` below the side sills as clearly indicated in Fig. 4. All the walls forming the hoppers are suitably braced, the side walls by the side stakes 37 and inclined diagonal-braces 384-38. he opening at the bottom of eachhopper is closed by two doors 18 each of -which is hinged at its outer edge by means of hinge brackets 19 pivotally connected to hinge butts 20 secured lon the outer side of the inner channel 11 forming the side sill'. Each door 18 is providedwith a depending flange 21 which extends around the end and inner edges' thereof, see F ig. 4. Bracing irons 22 and 23 are also secured to the under side of each door to properly strengthen the same. By referring to Fig. 4, it will be seen that the doors 18, when in closed position,vl incline inwardly and downwardly and at their outer portions are raised above the lower edge of the end walls 17 so that the closure at the ends of the pockets is effected by the edges of the end sheets 16 and 17 and the end portions of the depending flanges 21 of the door. In this way, I am enabled to obtain an increased capacity due to the fact that the end walls 17 may be placed nearer the ends of the cars than they otherwise could be, it being borne in mind that certain factors must always be taken into consideration in designing the cars such, for instance, as the inclination of the end sheets, the door opening area and the clearance which must be maintained between the doors and the trucks when the doors are open. Each iron 22, at its ends is provided with laterally extended projections 24 to which projections -are secured the bolts 25 forming the end link I of each Winding chain 26, the other end of each chain being pivotally secured to the drum 27 fixed to a transversely extending shaft 28. As clearly shown in Fig. 2, the winding chains and drums arearranged in pairs at each end of the doors so that rotation of the shafts 28 operates both doors for each pocket simultaneously. The shafts 28 which extend from side to side of the car, are each provided with a bevel gear 29, the

bevel gears 29-29 cooperating with bevel' gears 30 secured to the ends of a longitudi` versely extending shaft 35 andthe latchesl 34 being secured to the ends of a transversely extending shaft. 36. With this arrangement, l

it is apparent that the dogs and latches for each door operating mechanism may be operated from either side of the car, which is an important consideration, particularly in the ore carrying service where the operators are obliged to work on relatively narrow docks.

I have herein shown and described in detail, one embodiment of my improvement but the same is merely illustrative as I am aware that the invention' may be embodied in other structures without departing from the spirit of the invention and I contemplate all changes and modifications as come within the scope of the claims appended hereto.

I claim:

1., An ore car having'the total lengthv thereof from coupler center to coupler center to center of receptacles into which it is arranged to dump the load, said car being divided at the center longitudinally thereof,

intohoppers, the center'of each of said hopthetransverse center line of the car, the spacing ,of said hoppers vpermitting the 4dumping of the load into two adjacent receptacles-of a uniformly spaced series, with- -out -interference when in a train having inhaving 'a plurality of longitudinally arido 'ter a'multiple of the distance'from the vcen- `pers being approximately.equidistant from ranged hoppers intermediate the trucks, the
